ENVELOPE.

Application filed November 26, 1927. Serial No. 235,800.

This invention relates to envelopes as used for the mailing of lettersand advertising matter and has for its objects an envelope provided withmeans for rapidly tearing open the envelope and partially ejecting itscontents.

Briefly described my invention comprises an envelope with a stringincorporated in its folds with one end projecting for grasping with thefingers, and the string arranged in such a manner that when the envelopeis sealed with a letter or circular inside and the string pulled it willtear open one end of the envelope and also draw out the letter.

My improved envelope is shown in the accompanying drawings in which Fig.1 is a plan view of the envelope blank made in accordance with myinvention.

Fig. 2 shows the blank folded and gummed to form the envelope ready foruse.

Fig. 3 shows the envelope as sealed with a letter therein, and theenvelope torn open at one end and the letter partially ejected throughthe simple pulling of the string.

In the drawings I show the use of the well known flat or tape-like formof string, as it is easier to incorporate in the manufacture of myimproved envelope, though it is to be understood that no restriction isimplied thereby, as any kind of a string, tape or thin wire maybe usedto carry out the invention and therefore the use of the word string inthe appended elaimsis intended to embrace these equivalents.

In Fig. 1 the envelope blank consists of a front wall 1, lower flap 2,side flaps 3 and 3' and a sealing flap 4.

Lying against the inner side of the blank is a flat string 5 whichextends angularly from the tip of flap 3 to the lower corner A of theenvelope, thence parallel with flap 3' and projects beyond the blank fora short distance as shown at B.

This string is preferably lapped over the edge of flap 3 a shortdistance as shown at C and firmly gummed in place at this end. It isalso gummed in place at the corner A and at the point D so as tomaintain the extension B in the proper position when the blank is foldedto make the envelope, and preferably the string is additionally lightlygummed in place at intervals or along its entire length so that when aletter is insorted in the completed envelope it will not slide betweenthe string and the inner face of the envelope against which the stringis positioned.

Also to further guard the string from hav-, ing a card or stiff letterpaper shoved under it I ma cover the long run of the string with a hghtpaper flap 6 gummed at its upper edge at 7 to the panel 1 of theenvelope. The flap 6 is partially broken away in Fig. 1 to reveal thestring 5 in full lines beneath.

The blank assembled as in Fig. 1 is folded and gnmmed to form anenvelope as in Fig. 2 and with the sealing flap4 left unsealed for theinsertion of letter, cards, or other matter for mailing.

When a letter is inserted in the envelope it lies between the long run 5of the string and the short run 5 which secures to the Upon closing theenvelope by sealing flap 4 it additionally secures the end C of thestring in place and bends the projecting end B down against the back ofthe envelope as indicated by the dotted line B in F1 3, thus leavingnothing projecting beyond the contour of the closed envelope.

To open the sealed envelope it is held by the edges in one hand and theprojecting string grasped with the fingers of the other hand and pulledin direction of the dotted line and arrow of Fig. 3, with a result thatthe string will first cut open the end of the envelope and then as it ispulled further it will break away from the inner surface of the envelopeand by engaging the remote end 8 of the letter will force the same outof the envelope tothe point 8 as shown in Fig. 3.

Thus with a quick pull of the string the letter is instantly opened andits contents projected so that it may be easily taken in the fingers andremove entirely.

I claim:

1. A mailing envelope provided with a tearing string on its innersurface, said string secured at one end to one end flap of the envelope,thence passing angularly across said flap andinner front wall of theenvelope to a remote corner thereof, thence on said wall for the lengththereof and projecting beyond the same and passin over a portion of theclosing or sealing ap of the envelope and beyond the same in a mannerwhereby the closing of said last mentioned flap Will fold the stringwith its free end lying Within the contour of the envelope.

2. A mailing envelope provided with a tearing string on its innersurface said string secured at one end to one end flap of the envelope,thenee passing angular-1y across said flap and inner front Wall of theenvelope to a remote corner thereof, thence on said 10 wall for thelength thereof and projecting CARL JULIUS ERIGKSON.
